...设置一些变量，如“名称”“比特率”“大小”和“下载”，批量打印所有这些信息，如下所示：

我试过“Findstr”、“Find”、“SED”、“GREP”、“FART”，但我找不到正确的方法（一行和字符分隔符）......

我唯一能看到的就是这条线：

<!-- ================= -->  

我可以像使用 END 分隔符一样使用它，因为该行标志着 mp3 下载和打印信息的结束...

有人可以帮助我吗？

谢谢你

Answer 1

下面的批处理文件使用了您想要的数据位于“info mp3 here”行下方固定行数的事实。此外，根据数据在行中的位置提取数据。如果某些数据不遵循此规则，则程序将需要修改。

@echo off
setlocal EnableDelayedExpansion
findstr /N /C:"info mp3 here" %1 > "%~N1.tmp"
set lastLine=-1
(for /F "usebackq delims=:" %%a in ("%~N1.tmp") do (
   set /A skip=%%a-lastLine
   for /L %%i in (1,1,!skip!) do set /P info=
   set /P =& set /P name=
   for /L %%i in (1,1,4) do set /P download=
   set "name=!name:*<b>=!
   for /F "delims=<" %%n in ("!name!") do echo [Name]      %%n
   set "info=!info:<br />= !"
   set "info=!info:</div>=!"
   set bitrate=
   set lenght=
   set size=
   set value=
   for %%t in (!info!) do (
      if not defined value (
         set value=%%t
      ) else ( 
         if %%t equ kbps (
            set "bitrate=Bitrate: !value! kbps. "
            set value=
         ) else if %%t equ mb (
            set "size=Size: !value! mb."
            set value=
         ) else (
            set "lenght=Lenght: !value!. "
            set value=%%t
         )
      )
   )
   if defined value (
      set "lenght=Lenght: !value!. "
   )
   set info=!bitrate!!lenght!!size!
   if not defined info set info=NO INFO.
   echo [Info]      !info!
   set "download=!download:"=$!"
   for /F "tokens=4 delims=$" %%d in ("!download!") do echo [Download]  %%d
   set /A lastline=%%a+6
)) < %1
del "%~N1.tmp"

输出：

Answer 2

这是一个脚本，它将解析您想要的信息。

该脚本将您的 HTML 文件的名称作为参数。

输出被发送到一个文件，该文件的名称是通过将“.parsed”附加到输入文件名。

脚本顶部的注释对用于在 HTML 文件中定位所请求信息的模式进行了一些解释。

用制表符替换“TAB”的两个实例，并确保在每个制表符之前保留一个空格。

#!/bin/bash

# Parse HTML with sed, suppressing all unwanted lines
  # "Info" lines all start with a number (ignoring whitespace)
  # Bitrate and file size can be identified by looking for
  #   the unit (kbps, mb) immediately following the numeric data
  # Length is identified by the colon in the middle of numeric data
  # File names are delimited by <b> and </b>
  # Lines with the URL all contain Download</a>
  # The </a> isn't necessary, but I thought it would be safer to
  #   include it since one could imagine "Download" appearing in a file name
# Pipe output to Awk for reordering of the parsed lines
#   and addition of "NO INFO" lines where necessary

sed -n '
/^[ TAB]*[0-9]/ {
  s/^[ TAB]*/[Info]      /
  s/\([0-9]*:[0-9]*\)[^0-9]*/Length: \1. /
  s/\([0-9\.]* .bps\)[^0-9L]*/Bitrate: \1. /
  s/\([0-9\.]* .b\)[^p][^0-9LB]*/Size: \1. /
  p
}
/<b>/ {
  s|</b>.*||
  s|.*<b>\(.*\)|[Name]      \1|
  p
}
\|Download</a>| {
  s/^.*\(http:[^"]*\).*/[Download]  \1/
  p
}' $1 | awk 'BEGIN { no_info = "[INFO]      NO INFO.";
                     info = no_info }
             { if ($1 == "[Name]") name = $0;
                 else if ($1 == "[Info]") info = $0;
                 else {
                   printf("%s\n%s\n%s\n\n", name, info, $0);
                   info = no_info
                 } }' > $1.parsed
exit 0
